Can anyone recommend a leakdown tester that for sure comes with the right adapter to fit the spark plug sockets on the 2.5L engine? I was going to get the OTC 5609 https://www.amazon.com/dp/B0030EVL60?tag=wranglerorg-20 but alot of the reviews say it doesnt come with an adapter that fits the 4.0 and the plug sockets should be the same.
